Unable to pay for Monk's services as a private detective, middle-aged law student Julie Parlo offers him a trade--she'll help Monk become reinstated as a policeman with the SFPD if he'll help her find her missing grandmother. The only clue to the identity of the kidnappers is a roughly drawn lightning bolt on a note left at the grandmother's house, leading Stottlemeyer and Disher to suspect the former leader of an anti-Vietnam War group from the Seventies. But when the captain, anticipating Monk's reinstatement, invites Monk to help him with interrogation, Monk accidentally discovers that the suspect's tattoo doesn't match the symbol on the note--it has three humps instead of two. Meanwhile, the kidnappers order Julie to provide turkey dinners to the homeless in exchange for the return of the grandmother. Julie complies and her grandmother is returned safely, leading Stottlemeyer to put the case ""on the back burner."" True to her promise, Julie informs Monk of a loophole that will all

In yet another case of murder in a room locked from the inside, a music producer is found dead with bullets in his back, head. and chest, clearly neither an accident nor a suicide. But this time there's a further twist: the dead man's pet chimpanzee, Darwin, is caught with the murder weapon in his hand. Not wanting to make a monkey of himself by falsely accusing a chimpanzee of murder, Stottlemeyer takes the chimp into the interrogation room, tempting the animal to fire what he thinks is an empty gun. Meanwhile, Disher realizes that he's inadvertently given the captain a loaded gun and panic ensues. When the gun goes off, endangering not only Stottlemeyer but Disher, Monk, and Sharona as well, Stottlemeyer is persuaded that the chimp is guilty and is ready to allow animal control to put him to sleep. Sharona, however, is convinced that Darwin is innocent. In desperation, Sharona resorts to breaking and entering to rescue Darwin, persuading the most unlikely person imaginable to take hi

When John Ricca, author of a controversial and unfavorable biography of martial artist Sonny (""the Cobra"") Chow, is found dead in his home, all the evidence points to Chow as the murderer. Unfortunately for Captain Stottlemeyer, his chief suspect has been dead for six years. While Monk and Natalie (who's more interested in being reimbursed for her business expenses than in solving the case) visit Chow's former teacher, Master Zee, who claims that Chow died in his arms, Stottlemeyer resorts to having the corpse dug up to prove that, despite rumors to the contrary, Chow is indeed dead. A dental X-ray proving that the corpse is Chow leaves Monk to figure out who tried to frame the dead man for murder. On an inadvertent tip from Disher, an avid Cobra fan, Monk and Natalie visit the Sonny Chow museum, where Monk finds two important clues--a hairbrush that has been stolen from its case and replaced with a lookalike and the stamp that the museum proprietor placed on Natalie's hand so that she

When Monk, Natalie, and Julie get stuck in a traffic jam after a multi-car collision blocks the freeway, Monk gets out of the car to investigate. He soon deduces from the absence of skid marks and other clues that the young man in the overturned Volkswagen that caused the pile-up was murdered and his body placed in the car to make his death look like an accident. But the highway patrolman in charge of the ""accident"" scene wants nothing to do with Monk (or the not-very-successful lawyer who has latched onto him), and the mountains blocking the signal prevent Monk from calling Captain Stottlemeyer for an authorization to investigate. Monk briefly returns to Natalie's car, where he finds Julie in need of a bathroom and Natalie nursing an injured wrist. Unfortunately for them, Monk's mind is on the fatality, and he returns to the Volkswagen. The angry officer gives him the victim's name and occupation (environmental activist), but he still refuses to listen to Monk's evidence. Meanwhile, t

In the middle of the night, Monk receives a phone call from a drunken Stottlemeyer, who has gone to Las Vegas with Disher for a fellow officer's bachelor party. Stottlemeyer believes that a wealthy casino owner has murdered his wife, but he needs Monk's help to prove that the death wasn't an accident. Unfortunately, when Monk arrives in Vegas with Natalie the next morning, Stottlemeyer can't remember anything that happened the previous night--including how his pants happened to be thrown out the window. As Monk and Natalie explore the elevator where the woman died, interrogate witnesses, and reenact the death scene (with Monk in the role of victim), Stottlemeyer tries to retrace his steps and deal with Disher, who has become addicted to blackjack and fallen hopelessly deep into debt. When Monk, at Stottlemeyer's insistence, takes Disher's place at the blackjack table to win back his money, he figures out how the murder occurred as he simultaneously places winning bets, but the casino o

When Captain Stottlemeyer suspects that a suicide is really a murder, Monk confirms his suspicions by discovering that the victim, Joanne Raphelson, was too short to have used the stool she supposedly stood on to hang herself. But the next clue, the remains of an olive, a cherry, and a cocktail onion on a stirring stick, leads Monk to suspect that the murder was committed by an astronaut, Steve Wagner. A little research reveals a motive--Joanne was about to publish a book revealing that Wagner had abused her five years earlier. Now all Monk has to do is to prove that Wagner could commit the murder when he was in outer space.

During the investigation of an armored car heist involving the deaths of two drivers and the theft of valuable government bonds, Lt. Disher tries to convince Captain Stottlemeyer that he witnessed a murder while under anesthesia in the dentist's office. When one of the highjackers, Denny Jardeen, is found murdered, Disher insists that Jardeen is the man he saw Dr. Bloom and his assistant kill while he was sedated. Stottlemeyer still thinks that Disher was hallucinating, and Disher angrily leaves the force, deciding to revive his high school rock band, the Randy Disher Project, as an alternate means of earning his living. Meanwhile, the only clue to Jardeen's murder is two pairs of bruises each ten inches apart on the dead man's chest.
